The correct answer is:
A. 14x+6y= 10
-14X-35y=77
Further explanation:
One method of solving system of linear equations in two variables is elimination method. In this method, the co-efficient of one variable have to be equated so that variable can be removed to get the value of other variable.
Given equations are:
As we have to eliminate x, then the co-efficient of x will be equated. For this purpose both equations will be multiplied with some constant.
So,
multiplying equation one with 2
Multiplying equation 2 by -7
So,
The correct answer is:
A. 14x+6y= 10
-14X-35y=77

It would be 15 because the 35 people at most minus the 20 students equals 15 so that would be the greatest number of adults allowed to be there.
Hello there, and thank you for posting your question here on brainly.
A trapezoid is not possible to have for obtuse because it would look more like a diamond. Also, if it had 4 obtuse angles, it would have 6 sides.
Hope this helped!! ☺♥
Answer:
no
Step-by-step explanation:
Volume is a three-dimensional scalar quantity. The cost of the glass is $1312.24.
<h3>What is volume?</h3>
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Given the colony must be able to take a volume of 200,000 cubic meters, therefore, the diameter of the hemisphere will be,
The volume of Hemisphere = (2/3)πr³
200,000 = (2/3) × π × R³
R = 45.7
The area of the base of the hemisphere is,
Area of the base = πR² = π×(45.7) = 6561.185 meters²
Given the cost of glass is $0.20 per square meter, therefore, the cost of the glass of the base will be,
Cost of glass = 6561.185 × 0.20 = $1312.24
Hence, the cost of the glass is $1312.24.
